IronOCR 中 SEHException 和 AVX 支援的故障排除

Updated: 2026年6月29日

未處理的例外狀況：System.Runtime.InteropServices.SEHException

此問題通常出現在使用不支援AVX的較舊Xeon、Celeron、Pentium或Atom處理器的機器上。

對於不支援AVX的處理器的支援已在IronOCR版本2022.8.7804中新增，請升級到較新的版本。

// Example: Checking AVX support programmatically in C#
using System;

class ProcessorFeatures
{
    // Main method to check AVX support
    static void Main()
    {
        // Check if the machine's processor supports AVX
        if (IsAvxSupported())
        {
            Console.WriteLine("AVX is supported.");
        }
        else
        {
            Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
        }
    }

    // Function to determine if AVX is supported
    static bool IsAvxSupported()
    {
        return System.Runtime.Intrinsics.X86.Avx.IsSupported;
    }
}

// Example: Checking AVX support programmatically in C#
using System;

class ProcessorFeatures
{
    // Main method to check AVX support
    static void Main()
    {
        // Check if the machine's processor supports AVX
        if (IsAvxSupported())
        {
            Console.WriteLine("AVX is supported.");
        }
        else
        {
            Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
        }
    }

    // Function to determine if AVX is supported
    static bool IsAvxSupported()
    {
        return System.Runtime.Intrinsics.X86.Avx.IsSupported;
    }
}

在此範例程式碼中，我們使用System.Runtime.Intrinsics.X86.Avx.IsSupported屬性來確定處理器是否支援AVX指令。如果不支援AVX，建議確保您使用的IronOCR版本包含對不支援AVX處理器的支援。
